Step 3:

Next you need to cut your bottle big so you can fold the sides of the bottle around the piece of wood you cut.After folding the sides you need to use your tacks(or nails)and hammer to hold the plastic to the wood.Because the plastic will shrink and if it is not held to the wood the plastic will bend in all directions.

Step 4:

Then when your done tacking the plastic to your wood you need to pre-heat the oven to 550 degrees.While the oven is pre-heating you need to get a metal pan and a piece of tin foil to put on your pan.next you need to put your wood and cover on the pan standing up.It should only take 3 to 5 minutes to be done ,but you need to keep an eye on it because it could fall over.

Step 5:

When it done just take it out and let it cool for a couple of minutes.After it's done cooling down just take the tacks out and put on your mp3 player.
